What exactly is held in the Backup. Getting ready to change servers and I have a 1.8TB to move. I was curious if I set some items up on the new server are they written over from the backup of the old server? For example if I setup some recordings and have a recording on the new server, will I lose that information and will it be replaced by the backup? I will have to move the recordings during the night when no one is using that is why I am asking. Plus since I am using external drives, is there any reason why I shouldn't use exFAT for the drive, so if I move servers again I can just plug and play? I'm moving from a Windows server to a Mac server.
You can copy the Database folder first and restore using that, then copy the rest over when you have time. Most the 1.8TB is from your recordings.
ExFAT is fine and what we use for the Raspberry Pi DVR too
